Installation of transformer substations: technology, instruction, reviews

Energy at the present stage of development offers a highly efficient means of allocating the target resource between users. Major providers of electricity tend to use methods to support the necessary tension on the lines and minimize losses. In part, these problems are solved through the use of wiring materials with optimum characteristics. But this is not always possible, and alternatively, installation of transformer substations, providing support for the optimal parameters on the line. Most often, thus is realized the function of the Converter, the quality of which is determined by the characteristics of the installation, and the correctness of the works and installation works.

What is a transformer substation?

Typically, substations of this type form the whole complex of electrical installations, which perform the transformation and distribution of energy. Also in the complex are switchgear, control equipment and ancillary facilities, which since they are transformer substations. Depending on the application, this structure can perform different tasks. For example, in the composition of district rural infrastructure, installation of transformer substation is often performed with the purpose of lowering the voltage of the network, and resource allocation along the lines of consumer stations. Differentiating between themselves and the substation. Nowadays, mast, complete and facilities closed. Each type provides its own specifics operating and installation.

General technology of erection of substations

The Process of installation activities can be divided into three steps – preparation, construction work and construction equipment. At the first stage experts develop a kind of project that will be carried out delivery of the complete work item. Further, there are performed construction operations that are often expressed in the construction of the Foundation stones. For this dug pit, is the filling of bulk materials and the rack mounted. Thus preparing ground, which made installation of overhead transmission lines and transformer substations with surrounding hardware components.

As for the installation of electrical equipment, it often are transported in special cabinets with protective constructions, which are welded to the same racks or securely fixed in the Foundation construction solutions.

Manual installation of the mast substation

To set the station turns on a power transformer box, high voltage arresters, disconnector, fuses and distribution cabinets. Implementation of the project, again, consists of a conveyor actions, Assembly actions and direct installation of supports in the trenches, followed by installation of the main equipment set. Special attention is paid to the electrical connection of devices among themselves, followed by revision and adjustment of equipment.

The Actual installation of the mast transformer substation which organizes the connection between a high voltage line and electrical power unit, you'll be only a particular approach to the installation of supports. Depending on the arrangement of the equipment can be used a single support member, U-shaped and the end of the rack. And the installation of supports performs a crane, as, indeed, and the positioning of the main equipment of the transformer.

Manual installation package substations

Installation work in the case of complete substations also provide for the execution of transport activities, the installation of equipment on a cage basis, the reconciliation, tie bolts, welding operation, electrical connection components, cabling and configuration. Of particular importance is the Assembly of substations, which must be correctly performed connecting the terminals of the windings low voltage. Separate units are installed by turn – first with each component, removable plugs that cover the exposed end of the tire. Further with the sill removed lifting clamps are fastening.

It is Important to note that the installation of transformer substations requires constant monitoring of coincidence of the horizontal and vertical axes of the contacts. To manage these connections, by the way, even on a factory-ordered special switches.

Installation instruction enclosed substations

A Feature of the mounting works in the case of closed substations is their conduct in the building. Therefore, in the room where you plan to use this design, you must complete all finishing activities. Typically, the station units are placed in different rooms. Next, a high voltage is applied – power cable or overhead lines. Separate premises are allocated to both valves, and a fulltransformers are typically installed in two technical rooms. The installation of the transformer substation is realized on the Foundation with the subsequent seaming along the guide rails by means of a winch or chain block.

Installation of earthing equipment for substations

Done Correctly the grounding basis will ensure the prevention of dangerous for hardware circuits, and will allow time to activate emergency mode. The function of earthing is usually performed the natural objects of engineering infrastructure, including piping, cable sheath or metal construction. The geometric parameters of grounding device are determined by calculation – depending on the electrical resistance in the soil and the contained material. Circulated and installation of equipment of transformer substations with the use of artificial earths. In such cases, you can apply strips or rods of steel that are screwed into the ground.

Feedback about the performance of the Assembly

According to the reviews of the customers installation of transformer substations, the results show the best teams of specialists-generalists. It is important to understand that this work requires different skills from the point of view of professional training. The same reviews indicate the quality performance of their tasks by electricians, but on their inability to cope with the formation of the power fastening equipment. In addition, installation of transformer station is recommended only in good weather. This is important because precipitation is a major obstacle to the workflow at each stage, forcing the use of insulating materials.

Conclusion

Despite the similarity of modern substations with the same units that were used many years ago, the current principles of the electrical equipment of this type have the essential features. They largely determine what installation method and technology. Installation of transformer substations with automation and an abundance of protective systems, for example, allows for the possibility of interaction with a wide range of auxiliary installations.

Accordingly, at the stage of designing a working platform can provide and the possibility of expanding the local complex. Another thing is that not in every case justified, and the presence of an expensive automatic system, and the use of multi-component electrical modules.
